Abstract

Disclosed is a method for impregnating a thermoplastic polymer with an impregnation material such as a fragrance or pest control agent or pharmaceutical composition. A thermoplastic polymer is impregnated by (1) dissolving an impregnation material such as a fragrance or pest control agent or pharmaceutical composition material in a volatile swelling agent maintained at or near supercritical conditions for the volatile swelling agent, (2) swelling the thermoplastic polymer by contacting it at or near supercritical conditions for the volatile swelling agent with the impregnation material-laden volatile swelling agent and then (3) reducing the pressure so that the volatile swelling agent diffuses out of the thus impregnated thermoplastic polymer.
